Applioatiomfiled September 5, 1912. Serial No. 718,631.

To all whom it may concern:

Be it known that 1, WILLIAM A. Oven- BECK, a citizen of the UnitedStates, and a resident of Salt Lake City, in the county of Salt Lake andState of Utah, have invented a new and Improved Book-Marker, of whichthe following is a full, clear, and exact description.

This invention relates to book markers and has reference moreparticularly to the class comprising a member adapted to clamp a page.

An object of the invention is to provide an inexpensive and simple bookmarker that will have a firm grip on the paper and W111 not injure ormar the page in places of contact with it.

Another object of the invention is to provide a book marker that willequally well hold one or a few pages of a book or of paper in file andindicate their place.

Reference is to be had to the accompanying drawings, constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views and in which Figure 1 is a planview of an embodiment of my invention; Fig. 2 is a section on line 2-2of Fig. 1; Fig. 3 is a side view of same in operation; and Fig. 4 is aplan view of the two parts forming the device.

Before proceeding to a more detailed description of my device, it mustbe understood that while the drawing discloses the invention formed oftwo fiat resilient members riveted together, the same may be punched outfrom a single piece and then properly folded, the upper portion pressedtogether and thereby obtaining the same effect as with the rivets.

The marker can be made of any metal suited for the purpose, and theupper partof the device may be numbered, lettered or otherwise marked asmeans for identification.

The device may be oxidized,,enameled or otherwise covered so as not tobe injured by the atmospheric conditions and mark the paper when incontact.

Referring to the drawings, 10 is a page magnified in thickness and it isclamped by the lower part or jaws of members 11 and 12 one on each sideof the page, the clamping action of the jaws bein due to the resiliencyof the material ad ed by the rivets 13 binding the members 11 and 12,and by the curved portions 14 and 15 formed preferably ,mldway betweenthe extremities of these members 11 and 12, said curved portions formingsprings for the jaws engaging the ObJGCt. The bent portions 14 and 15are increased in resiliency by providing an orifioe 16 in the member 11and the curved portions 14, and by cutting out similar notches 17 ateach side of the member 12 also in the curved portion 15. This reductionin material gives more resiliency to the members 11 and 12 and alsopermits the curved portion 15 to project through the orifice 16, whilethe curved portions 14 will register with notches 17 as best shown inFigs. 2 and 3. The curved portions 14 and 15 of the members 11 and 12are preferably elliptical in curvature so that when the members arebound together by means of rivets 13, the curved portions will afford alarge sur face and, therefore, an easy grip for fingers of the hand, theupper part of the device being provided with the numeral fordistinguishing from similar markers when used together. When the markeris to be placed in a desired position, the fingers are applied to thecurved parts 14 and 15 of members 11 and 12, and forcing the fingerstoward each other, the lower part of members 11 and 12 or the jaws arespaced so as to admit the page or pages desired.

As can be seen from Fig. 2, the lower part of the members 11 and 12 arecloser together at their extremity so as to make the contact surfacebetween the jaws and the paper increase until the two jaws are parallelthat will clamp the paper by bearing against it with their entiresurface and thus insure a good and even grip on the same.

It must also be remarked that my book marker can also be used as a paperfastener simultaneously as a marker for loose papers inclosed in a fileof other papers.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A device of the class described comprising a pair of members injuxtaposition, each of said members having intermediate its ends abulged portion, said members havin openings in said bulged portionswhere y said portions extend past each other, each of said members,wit-h the exception of its bulged portion being wholly at one side ofthe other of said members and means binding said members at one end andtherer by forming the fulcrum for the opposite ends which are adapted toengage the page of a book, said ends normally converging toward eachother from the bulged portion of the members.

2. A device of the class described comprising a pair of resilientmembers, one of said members having a central "aperture intermediate itsends and the other of said memhers having notches intermediate its endsat the sides thereof, the said members having a bulged portion formedwhere said aperture and said notches respectively are provided in saidmembers, said members having the same sides opposite each other throughthe entire length with the exception of said bulged portions, and saidbulged portion of one of said members passing through the aperture ofthe other of said members, and the bulged portion of the othersaidmember passing through the notches of said first member; means at oneend of said members bindin them together and forming a fulcrum %or saidmembers, and the opposite ends of said members diverging from theextremities toward the bulging portions.

In testimony whereof I have signed my.

name to this specification in the presence of i two subscribingwitnesses.
